Security audit

私人AI助理选型与试用助手

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed assistant-selection workflow with an optional AI-HIVE connection and local result checker; I found no hidden or destructive behavior.

Before installing, be aware this is primarily a Chinese-language workflow and may optionally connect to AI-HIVE through web login or MCP/OAuth. Keep credentials out of chat, authorize uploads or paid actions only for a clearly defined task and budget, and review generated scorecards and external receipts before relying on them.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection

Finding

The declared description promises a user-facing assistant-selection helper that analyzes preferences and produces trial questionnaires, CSV scorecards, and selection advice. The supplied code does none of that. Its primary purpose is to validate a saved result schema/contract and local artifact integrity, including status consistency, authorization references for mutating actions, provenance fields, and SHA-256 checks. While it does not perform dangerous undeclared external actions, its core functionality is materially different and unrelated to the declared product behavior. Therefore this is a clear description-behavior mismatch.

Without declared permissions the skill's intent is opaque and cannot be validated.

Finding

This markdown file presents all operational instructions exclusively in Chinese, which can amount to a language policy violation when no user opt-in or justified locale constraint is provided. The document does not state that the skill is region-specific or offer an alternative language.

Finding

The natural-language note is written only in Chinese: '空值供用户按实际任务填写,不填密码、Token、验证码、Cookie或完整证件信息。' For a general intake file with no stated regional or compliance scope, this imposes a language expectation without user opt-in or an explicit locale justification.

Intent-Code Divergence

Confidence

Finding

The docstring presents the tool as if it performs no actions, yet the implementation reads result files, traverses artifact paths under a supplied root, checks file metadata, and hashes file contents. While these are local-only operations and not remote actions, the wording "executes actions" is broader than the actual behavior and can mislead about side effects and file access.
